Consider a spring-mass system with the following parameters：m=1x10-6kg, k=1 n/m, b= 1x10-6 ns/m. calculate the natural frequency f0 and quality factor q. assume the input force f=0.001sin2ft (unit: newton). calculate and sketch the steady-state waveforms of the displacement when f=f0. clearly indicate the phase and amplitude of the displacement waveform. hint: the displacement will be sinusoidal function as well. use the transfer function to calculate the amplitude and phase of the displacement.

Amoving company collects data about couches they move and displays the data in a table. the force along the ramp, the angle of the ramp, and the height the couch is raised to are shown. which statements correctly compare the work done to move the couches? check all that apply. the same amount of work is done for couches 1 and 3. the same amount of work is done for couches 2 and 3. the work for couch 1 is greater than the work for couch 2. the work for couch 2 is less than the work for couch 3. the work for couch 3 is greater than the work for couch 1. the work for couch 2 is greater than the work for couch 1.
